design-control-loop

A plugin for designing and building an agentic control loop: a repeating system where sensors observe a codebase, a controller decides what to do, and an actuator makes changes. It includes a design interview and locally runnable components with a scheduled GitHub Actions workflow.

In plain words
What is it for?
Use it to design recurring coding-agent automation for a repository, define observation and decision steps, build local loop components, and run the process through scheduled GitHub Actions.
Why use it?
It helps turn an ongoing coding task into a repeatable process that can observe changes, make decisions, and act on a schedule. The control-loop model also accounts for disturbances that may affect the work.

Grade A, and why

design-control-loop scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
